Growth differentiation factor-15 and metabolic features in chronic heart failure: Insights from the SUPPORT Trial -GDF15 across the BMI spectrum.

BACKGROUND: GDF15 plays pivotal metabolic roles in nutritional stress and serves as a physiological regulator of energy balance. However, the patterns of GDF15 levels in underweight or obese patients with chronic heart failure (CHF) are not well-understood. METHODS: We assessed serum GDF15 levels at baseline and 3 years and the temporal changes in 940 Japanese patients (642 paired samples), as a sub-analysis of the SUPPORT trial (age 65.9 ± 10.1 years). The GDF15 levels were analyzed across BMI groups (underweight [<18.5 kg/m2; n = 50], healthy weight [18.5-22.9; n = 27 5], overweight [23-24.9; n = 234], and obese [≥25; n = 381]), following WHO recommendations for the Asian-Pacific population. Landmark analysis at 3 years assessed the association between GDF15 levels and HF hospitalization or all-cause death. RESULTS: Compared to the healthy weight group, the underweight group included more females (54.0%) with advanced HF (NYHA class III; 20.0%) and exhibited increased GDF15 level (1764 pg/mL [IQR 1067-2633]). Obese patients, younger (64.2 years) and diabetic (53%), had a similar GDF15 level to the healthy weight group. A higher baseline GDF15 level was associated with worse outcomes across the BMI spectrum. GDF15 increased by 208 [21-596] pg/mL over 3 years, with the most substantial increase observed in the underweight group (by +28.9% [6.2-81.0]). Persistently high GDF15 levels (≥1800 pg/mL) was independently associated with worse outcomes after 3 years (adjusted HR 1.8 [95%CI 1.1-2.9]). CONCLUSIONS: In underweight patients with CHF, GDF15 level was elevated at baseline and experienced the most significant increase over 3 years. Its consistent elevation suggested a worse outcome.

Continuous and Early Progression of Carotid Intima-Media Thickness after Radiotherapy for Head and Neck Cancer: 5-Year Prospective Observational Study.

INTRODUCTION: Radiation-induced carotid artery stenosis (RI-CS) is known as one of long-term side effects of radiotherapy for head and neck cancer (HNC). However, the clinical time course after irradiation has been poorly understood. We aimed to investigate the natural history of radiation-induced carotid atherosclerosis, comparing the patients who received radiotherapy for HNC with the patients who were treated without radiotherapy. METHODS: The patients who received treatment of HNC at Department of Otolaryngology, Head and Neck Surgery of Kyoto University Hospital, from November 2012 to July 2015 were enrolled. The patients were assigned into the RT group and the control group, depending on whether radiotherapy was planned or not. Annual carotid ultrasound was performed from the enrollment to 5 years. The increase of mean intima-media thickness (IMT) at common carotid artery from the enrollment (Δmean IMT) was evaluated. RESULTS: Fifty-six patients in the RT group and 25 patients in the control group were enrolled. From 5-year follow-up data, the significant higher increase of Δmean IMT was consistently observed in the RT group than in the control group after 2 years. The RT group presented a 7.8-fold increase of mean IMT compared to the control group (0.060 mm per year in the RT group and 0.008 mm per year in the control group). Cumulative incidence curves obtained from the analysis of all vessels revealed that the RT group presented higher incidence of Δmean IMT ≥0.25 mm than the control group (p < 0.01). In the RT group, the patients with mean IMT ≥1.0 mm at enrollment exhibited significantly higher incidence of Δmean IMT ≥0.25 mm than the patients with mean IMT <1.0 mm (p < 0.01). DISCUSSION: Radiotherapy for HNC induces continuous carotid mean IMT progression. The irradiated carotid arteries with mean IMT ≥1.0 mm before radiotherapy presented earlier IMT progression than those with mean IMT <1.0 mm.

Sex Differences in Clinical Outcomes After Percutaneous Coronary Intervention.

BACKGROUND: There is a scarcity of studies comparing the clinical outcomes after percutaneous coronary intervention (PCI) for women and men stratified by the presentation of acute coronary syndromes (ACS) or stable coronary artery disease (CAD).Methods and Results: The study population included 26,316 patients who underwent PCI (ACS: n=11,119, stable CAD: n=15,197) from the CREDO-Kyoto PCI/CABG registry Cohort-2 and Cohort-3. The primary outcome was all-cause death. Among patients with ACS, women as compared with men were much older. Among patients with stable CAD, women were also older than men, but with smaller difference. The cumulative 5-year incidence of all-cause death was significantly higher in women than in men in the ACS group (26.2% and 17.9%, log rank P<0.001). In contrast, it was significantly lower in women than in men in the stable CAD group (14.2% and 15.8%, log rank P=0.005). After adjusting confounders, women as compared with men were associated with significantly lower long-term mortality risk with stable CAD but not with ACS (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.69-0.82, P<0.001, and HR: 0.92, 95% CI: 0.84-1.01, P=0.07, respectively). There was a significant interaction between the clinical presentation and the mortality risk of women relative to men (interaction P=0.002). CONCLUSIONS: Compared with men, women had significantly lower adjusted mortality risk after PCI among patients with stable CAD, but not among those with ACS.

Nephrotic Syndrome as an Extramuscular Manifestation of Anti-EJ Antibody-Positive Dermatomyositis: A Case Report and Review of the Literature.

Renal involvement is underestimated as an extramuscular manifestation of dermatomyositis (DM). Here, we describe a 67-year-old woman with anti-glycyl-transfer ribonucleic acid synthetase (anti-EJ) antibody and anti-ribonucleoprotein antibody-positive DM complicated by systemic sclerosis, who developed nephrotic syndrome concurrently with the exacerbation of DM, as indicated by incremental serum creatine kinase levels, high-intensity lesions on muscle magnetic resonance imaging, and active interstitial pneumonitis on chest computed tomography. Renal biopsy revealed the presence of immune-deposition in the glomerulus by immunofluorescence. To our knowledge, this is the first report describing the coexistence of anti-EJ antibody-positive DM and nephrotic syndrome. More reports of similar cases are warranted to substantiate the association.

Percutaneous coronary intervention using new-generation drug-eluting stents versus coronary arterial bypass grafting in stable patients with multi-vessel coronary artery disease: From the CREDO-Kyoto PCI/CABG registry Cohort-3.

AIMS: There is a scarcity of studies comparing percutaneous coronary intervention (PCI) using new-generation drug-eluting stents (DES) with coronary artery bypass grafting (CABG) in patients with multi-vessel coronary artery disease. METHODS AND RESULTS: The CREDO-Kyoto PCI/CABG registry Cohort-3 enrolled 14927 consecutive patients who underwent first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013. The current study population consisted of 2464 patients who underwent multi-vessel coronary revascularization including revascularization of left anterior descending coronary artery (LAD) either with PCI using new-generation DES (N = 1565), or with CABG (N = 899). Patients in the PCI group were older and more often had severe frailty, but had less complex coronary anatomy, and less complete revascularization than those in the CABG group. Cumulative 5-year incidence of a composite of all-cause death, myocardial infarction or stroke was not significantly different between the 2 groups (25.0% versus 21.5%, P = 0.15). However, after adjusting confounders, the excess risk of PCI relative to CABG turned to be significant for the composite endpoint (HR 1.27, 95%CI 1.04-1.55, P = 0.02). PCI as compared with CABG was associated with comparable adjusted risk for all-cause death (HR 1.22, 95%CI 0.96-1.55, P = 0.11), and stroke (HR 1.17, 95%CI 0.79-1.73, P = 0.44), but with excess adjusted risk for myocardial infarction (HR 1.58, 95%CI 1.05-2.39, P = 0.03), and any coronary revascularization (HR 2.66, 95%CI 2.06-3.43, P<0.0001). CONCLUSIONS: In this observational study, PCI with new-generation DES as compared with CABG was associated with excess long-term risk for major cardiovascular events in patients who underwent multi-vessel coronary revascularization including LAD.

Coronary Artery Disease Without Standard Cardiovascular Risk Factors.

Recently, one observational study showed that patients with ST-segment elevation myocardial infarction (STEMI) without standard cardiovascular risk factors were associated with increased mortality compared with patients with risk factors. This unexpected result should be evaluated in other populations including those with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and chronic coronary syndrome (CCS). Among 30,098 consecutive patients undergoing first coronary revascularization in the CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Grafting) registry cohort-2 and 3, we compared clinical characteristics and outcomes between patients with and without risk factors stratified by their presentation (STEMI n = 8,312, NSTE-ACS n = 3,386, and CCS n = 18,400). Patients with risk factors were defined as having at least one of the following risk factors: hypertension, dyslipidemia, diabetes, and current smoking. The proportion of patients without risk factors was low (STEMI: 369 patients [4.4%], NSTE-ACS: 110 patients [3.2%], and CCS: 462 patients [2.5%]). Patients without risk factors compared with those with risk factors more often had advanced age, low body weight, and malignancy and less often had history of atherosclerotic disease and prescription of optimal medical therapy. In patients with STEMI, patients without risk factors compared with those with risk factors were more often women and more often had atrial fibrillation, long door-to-balloon time, and severe hemodynamic compromise. During a median of 5.6 years follow-up, patients without risk factors compared with those with risk factors had higher crude incidence of all-cause death. After adjusting confounders, the mortality risk was significant in patients with CCS (hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.01 to 1.49, p = 0.04) but not in patients with STEMI (HR 1.06, 95% CI 0.89 to 1.27, p = 0.52) and NSTE-ACS (HR 1.07, 95% CI, 0.74 to 1.54, p = 0.73). In conclusion, among patients undergoing coronary revascularization, patients without standard cardiovascular risk factors had higher crude incidence of all-cause death compared with those with at least one risk factor. After adjusting confounders, the mortality risk was significant in patients with CCS but not in patients with STEMI and NSTE-ACS.

Effect of Heart Failure on Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Severe Coronary Artery Disease.

Background Heart failure might be an important determinant in choosing coronary revascularization modalities. There was no previous study evaluating the effect of heart failure on long-term clinical outcomes after percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG). Methods and Results Among 14 867 consecutive patients undergoing first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013 in the CREDO-Kyoto PCI/CABG registry Cohort-3, we identified the current study population of 3380 patients with three-vessel or left main coronary artery disease, and compared clinical outcomes between PCI and CABG stratified by the subgroup based on the status of heart failure. There were 827 patients with heart failure (PCI: N=511, and CABG: N=316), and 2553 patients without heart failure (PCI: N=1619, and CABG: N=934). In patients with heart failure, the PCI group compared with the CABG group more often had advanced age, severe frailty, acute and severe heart failure, and elevated inflammatory markers. During a median 5.9 years of follow-up, there was a significant interaction between heart failure and the mortality risk of PCI relative to CABG (interaction P=0.009), with excess mortality risk of PCI relative to CABG in patients with heart failure (HR, 1.75; 95% CI, 1.28-2.42; P<0.001) and no excess mortality risk in patients without heart failure (HR, 1.04; 95% CI, 0.80-1.34; P=0.77). Conclusions There was a significant interaction between heart failure and the mortality risk of PCI relative to CABG with excess risk in patients with heart failure and neutral risk in patients without heart failure.

Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Versus Without Chronic Kidney Disease.

Chronic kidney disease (CKD) might be an important determinant in choosing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). However, there is a scarcity of studies evaluating the effect of CKD on long-term outcomes after PCI relative to CABG in the population including severe CKD. Among 30257 consecutive patients patients who underwent first coronary revascularization with PCI or isolated CABG in the CREDO-Kyoto PCI/CABG registry Cohort-2 (n = 15330) and Cohort-3 (n = 14,927), we identified the current study population of 12,878 patients with multivessel or left main disease, and compared long-term clinical outcomes between PCI and CABG stratified by the subgroups based on the stages of CKD (no CKD: eGFR >=60 ml/min/1.73m2, moderate CKD: 60> eGFR >=30 ml/min/1.73m2, and severe CKD: eGFR <30 ml/min/1.73m2 or dialysis). There were 6,999 patients without CKD (PCI: n = 5,268, and CABG: n = 1,731), 4,427 patients with moderate CKD (PCI: n = 3,226, and CABG: n = 1,201), and 1,452 patients with severe CKD (PCI: n = 989, and CABG: n = 463). During median 5.6 years of follow-up, the excess mortality risk of PCI relative to CABG was significant regardless of the stages of CKD without interaction (no CKD: HR, 1.36; 95%CI, 1.12 to 1.65; p = 0.002, moderate CKD: HR, 1.40; 95%CI, 1.17 to 1.67; p <0.001, and severe CKD: HR, 1.33; 95%CI, 1.09 to 1.62; p = 0.004, Interaction p = 0.83). There were no significant interactions between CKD and the effect of PCI relative to CABG for all the outcome measures evaluated. In conclusion, PCI compared with CABG was associated with significantly higher risk for all-cause death regardless of the stages of CKD without any significant interaction.

ECG Changes Through Immunosuppressive Therapy Indicate Cardiac Abnormality in Anti-MDA5 Antibody-Positive Clinically Amyopathic Dermatomyositis.

Anti-melanoma differentiation-associated gene 5 (MDA5) antibody, a dermatomyositis (DM)-specific antibody, is strongly associated with interstitial lung disease (ILD). Patients with idiopathic inflammatory myopathy (IIM) who are anti-MDA5 antibody positive [anti-MDA5 (+)] often experience chest symptoms during the active disease phase. These symptoms are primarily explained by respiratory failure; nevertheless, cardiac involvement can also be symptomatic. Thus, the aim of this study was to investigate cardiac involvement in anti-MDA5 (+) DM. A total of 63 patients with IIM who underwent electrocardiography (ECG) and ultrasound cardiography (UCG) during the active disease phase from 2016 to 2021 [anti-MDA5 (+) group, n = 21; anti-MDA5-negative (-) group, n = 42] were enrolled in the study, and their clinical charts were retrospectively reviewed. The ECG and UCG findings were compared between the anti-MDA5 (+) and anti-MDA5 (-) groups. All anti-MDA5 (+) patients had DM with ILD. The anti-MDA5 (+) group showed more frequent skin ulcerations and lower levels of leukocytes, muscle enzymes, and electrolytes (Na, K, Cl, and Ca) than the anti-MDA5 (-) group. According to the ECG findings obtained during the active disease phase, the T wave amplitudes were significantly lower for the anti-MDA5 (+) group than for the anti-MDA5 (-) group (I, II, and V4-6 lead; p < 0.01; aVF and V3, p < 0.05). However, the lower amplitudes were restored during the remission phase. Except for the E wave, A wave and Sep e', the UCG results showed no significant differences between the groups. Four patients with anti-MDA5 (+) DM had many leads with lower T wave and cardiac abnormalities (heart failure, diastolic dysfunction, myocarditis) on and after admission. Though anti-MDA5 (+) patients clinically improved after immunosuppressive therapy, some of their ECG findings did not fully recover in remission phase. In conclusion, anti-MDA5 (+) DM appears to show cardiac involvement (electrical activity and function) during the active phase. Further studies are necessary to clarify the actual cardiac condition and mechanism of these findings in patients with anti-MDA5 (+) DM.

Periprocedural Stroke After Coronary Revascularization (from the CREDO-Kyoto PCI/CABG Registry Cohort-3).

There is a scarcity of data on incidence, risk factors, especially clinical severity, and long-term prognostic impact of periprocedural stroke after coronary revascularization in contemporary real-world practice. Among 14,867 consecutive patients undergoing first coronary revascularization between January 2011 and December 2013 (percutaneous coronary intervention [PCI]: N = 13258, and coronary artery bypass grafting [CABG]: N = 1609) in the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG registry Cohort-3, we evaluated the details on periprocedural stroke. Periprocedural stroke was defined as stroke within 30 days after the index procedure. Incidence of periprocedural stroke was 0.96% after PCI and 2.13% after CABG (log-rank p <0.001). Proportions of major stroke defined by modified Rankin Scale ≥2 at hospital discharge were 68% after PCI, and 77% after CABG. Independent risk factors of periprocedural stroke were acute coronary syndrome (ACS), carotid artery disease, advanced age, heart failure, and end-stage renal disease after PCI, whereas they were ACS, carotid artery disease, atrial fibrillation, chronic obstructive pulmonary disease, malignancy, and frailty after CABG. There was excess long-term mortality risk of patients with periprocedural stroke relative to those without after both PCI and CABG (hazard ratio 1.71 [1.25 to 2.33], and hazard ratio 4.55 [2.79 to 7.43]). In conclusion, incidence of periprocedural stroke was not negligible not only after CABG, but also after PCI in contemporary real-world practice. Majority of patients with periprocedural stroke had at least mild disability at hospital discharge. ACS and carotid artery disease were independent strong risk factors of periprocedural stroke after both PCI and CABG. Periprocedural stroke was associated with significant long-term mortality risk after both PCI and CABG.

Development of Eosinophilic Temporal Arteritis and Digital Ischemia in a Patient with Hypereosinophilic Syndrome.

We describe a case of eosinophilic temporal arteritis in a 61-year-old woman with hypereosinophilic syndrome, who developed subcutaneous nodules in the temporal areas and digital cyanosis with small nodules on the sides of her fingers. Ultrasound revealed occlusion and corkscrew-like changes of the temporal and digital arteries, respectively. Temporal artery biopsy revealed eosinophilic vasculitis without giant cell formation. Angiography showed occlusion of the ulnar and digital arteries. Administration of low-dose corticosteroid improved the temporal artery swelling and digital cyanosis. More reports of similar cases are required to characterize this type of non-giant cell eosinophilic vasculitis that affects the peripheral arteries.

Diabetes Mellitus and Long-Term Risk for Heart Failure After Coronary Revascularization.

BACKGROUND: The effect of diabetes mellitus (DM) status on the long-term risk for heart failure (HF) in patients undergoing coronary revascularization has not been adequately evaluated.Methods and Results:In this study, 15,231 patients who underwent coronary revascularization in the CREDO-Kyoto Registry Cohort-2 were divided into 2 groups according to DM status (DM group: n=5,999; Non-DM group: n=9,232). The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM [ITDM]: n=1,353; non-insulin-treated DM [NITDM]: n=4,646). The primary outcome measure was HF hospitalization. The cumulative 5-year incidence of HF hospitalization was significantly higher in the DM than non-DM group (11.0% vs. 6.6%, respectively; log-rank P<0.0001), and in the ITDM than NITDM group (14.6% vs. 10.0%, respectively; log-rank P<0.0001). After adjusting for confounders, the increased risk of HF hospitalization with DM relative to non-DM remained significant (hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.30-1.67, P<0.0001), whereas the risk associated with ITDM relative to NITDM was not significant (HR 1.17, 95% CI 0.96-1.43, P=0.12). CONCLUSIONS: The adjusted long-term risk for HF hospitalization after coronary revascularization was significantly higher in DM than non-DM patients, regardless of revascularization strategy, but did not differ between ITDM and NITDM patients.

DECLARE-TIMI 58: Participants' baseline characteristics.

AIM: To describe the baseline characteristics of participants randomized in the Dapagliflozin Effect on CardiovascuLAR Events (DECLARE-TIMI 58) trial, the pivotal study conducted to assess cardiovascular (CV) outcomes with dapagliflozin. METHODS: The DECLARE-TIMI 58 trial will analyse 17 160 patients with type 2 diabetes randomized to treatment with dapagliflozin (10 mg/d) or matching placebo. We analysed their baseline characteristics. RESULTS: The participants' mean ± SD age was 63.8 ± 6.8 years, 62.6% were male, and their mean ± SD diabetes duration was 11.8 ± 7.8 years, glycated haemoglobin 8.3% ± 1.2% (67 mmol/mol ± 9.7 mmol/mol) and body mass index 32.1 ± 6.0 kg/m2 . Randomization included 6971 (40.6%) patients with atherosclerotic CV disease (CVD), and 10 189 (59.4%) patients with multiple risk factors (MRF) for CVD (defined as men age ≥ 55 years or women ≥60 years, with at least one of dyslipidaemia, hypertension or smoking). Patients with CVD compared with patients with MRF were younger (62.5 ± 8.1 vs 64.7 ± 5.6 years), more frequently male (72.1% vs 56.1%), less often used metformin (74.6% vs 81.2%), more often used insulin (44.2% vs 36.4%), and more frequently used statins, aspirin, clopidogrel and ß-blockers (82.2%, 71.1%, 24.7% and 66.6% vs 63.7%, 39.1%, 1.5% and 32.3%, respectively). CONCLUSION: The DECLARE-TIMI 58 trial is expected to provide conclusive data on the effect of treatment with dapagliflozin in addition to standard of care, on CV outcomes in a broad patient population with type 2 diabetes and CVD or MRF for CVD.

Granulomatosis with Polyangiitis Complicated by Hypertrophic Pachymeningitis Presenting with Simultaneous Multiple Intracerebral Hemorrhages.

Central nervous system (CNS) involvement in granulomatosis with polyangiitis (GPA), including pachymeningitis and CNS vasculitis, is uncommon. Although intracerebral hemorrhage (ICH) has been reported in GPA, simultaneous multiple ICH (SMICH) is rare. We describe the case of a 50-year-old woman with a history of a limited form of GPA with chronic pachymeningitis who presented with acute-onset headache accompanied by nausea and vomiting, and who developed consciousness impairment. Computed tomography revealed bilateral subcortical ICH. Sinus thrombosis was not apparent on angiography. The patient was treated with high-dose corticosteroid therapy. The cause of the steroid-responsive SMICH in this case was unknown, but it might have been CNS vasculitis. Patients with GPA may present with SMICH, which is considered an indication for immunosuppressive therapy.
